minus-squareBlue_Morpho@lemmy.worldlinkfedilinkEnglisharrow-up7·2 days agoThe wiggle isn’t only on the surface. I’d bet it is everywhere except for the surface or users would complain about defects. So if you sand the surface, the forensics slices it in half and reads the wiggle that is embedded everywhere inside.
